Description

Technical Field

[0001] The present application relates to the field of coal mine safety technology, and in particular to a method for detecting temperature in a mine area based on magnetic induction technology. Background Art

[0002] There are two main methods for existing mine temperature monitoring, namely bundle tube monitoring and optical fiber temperature measurement monitoring.

[0003] Regarding bundle tube monitoring, the gas sample inside the mine is collected to the ground through a vacuum pump, and then analyzed by a chromatograph. However, there are still the following problems with bundle tube monitoring: 1. The laying distance of the bundle tube cable from the bundle tube monitoring room to the sampling point is long, and there are certain joints in the pipeline, which is prone to blockage and leakage. Therefore, the maintenance workload during use will be very large. If the maintenance work cannot keep up, the bundle tube monitoring system will be unusable for a period of time in the future; 2. The stability and reliability of the existing gas chromatograph need to be further strengthened; 3. Because the bundle tube pipeline is too long, it takes hours for the ground vacuum pump to pump the underground gas to the ground, which means that the underground gas changes will occur after several hours. It may be detected on the ground only after a certain time lag; 4. The number of routes that the bundle tube monitoring system can monitor and analyze is limited. Specifically, in many coal mines, these monitoring routes are relatively small, and when old monitoring points are abolished and new monitoring points are established, pipelines need to be re-laid, which increases the output of manpower and material resources; 5. Bundle tube monitoring mainly analyzes gases, and the monitoring points are relatively far back, and spontaneous combustion areas cannot be predicted; 6. The bundle tube monitoring system includes dust filters, single tubes, bundle tubes, water vapor filters, branch boxes, vacuum pumps, gas sampling control cabinets, monitoring computers, bundle tube-specific chromatographs and other equipment. The entire system is relatively complex, with many equipment failure points and poor system reliability.

[0004] Compared with bundle tube monitoring, fiber optic temperature monitoring has the advantages of convenient layout and high data collection efficiency. However, fiber optic temperature detection still has the following problems: 1. Temperature measurement optical fiber can only be arranged in the chute area and cannot monitor the internal area of ​​the working face; 2. The optical fiber is easily broken by falling gangue in the goaf and cannot be repaired, which will cause the loss of position information. The loss of position information will cause the accuracy of the system's calculated temperature to drop significantly; 3. The fiber optic testing system involves complex software algorithms, and the temperature measurement results have large errors.

[0005] In view of this, according to the defects of optical fiber temperature monitoring, people have proposed a wireless transmission system based on electromagnetic waves. However, since the temperature sensor is buried deep under the gangue in the goaf, the gangue has a significant shielding effect on electromagnetic waves, resulting in limited data transmission distance. If the accuracy of temperature data collection is to be guaranteed, a large number of wireless temperature sensors need to be deployed, which is costly. In addition, changes in moisture content in the goaf will also seriously affect the data transmission distance, resulting in unstable data transmission.

[0006] From the above, it can be seen that the existing mining area temperature detection methods have the problem of affecting the temperature detection accuracy during the transmission of the collected data. Therefore, a new mining area temperature detection method is urgently needed to solve the above problems. Summary of the invention

[0040] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

The singular forms of "a", "said" and "the" used in one or more embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used in one or more embodiments of the present application refers to and includes any or all possible combinations of one or more associated listed items.

[0042] It should be understood that, although the terms first, second, etc. may be used to describe various information in one or more embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0043] In the present application, a method for detecting temperature in a mining area based on magnetic induction technology is provided, which is described in detail in the following embodiments.

[0044] Figure 1 A flow chart of a method for detecting temperature in a mining area based on magnetic induction technology according to an embodiment of the present application is shown, which specifically includes the following steps:

[0045] Step S102: collecting temperature information at different positions in the goaf through temperature sensors arranged in the goaf;

[0046] Step S104: Based on a preset information transmission strategy, the temperature sensor transmits the temperature information to an information processing device through magnetic induction;

[0047] Step S106: determining a spontaneous combustion risk area through the information processing device according to the temperature information;

[0048] Step S108: Displaying the spontaneous combustion risk area through a preset display device.

[0049] In the coal mining area operation scene, hydraulic supports are usually arranged in the mining area for support. The area where coal mining is completed is the goaf. At this time, the hydraulic supports will move forward, causing the original support area to collapse naturally without hydraulic supports. Most of the goaf is gangue, but a small amount of coal will be left. Under the premise of a certain thickness, if the ambient oxygen concentration is appropriate, this part of the leftover coal will accumulate and oxidize over a period of time, generating heat energy, and eventually leading to spontaneous combustion.

[0050] Based on this, a controller is arranged on the hydraulic support, and a certain number of temperature sensors are stored in the controller. The hydraulic support continues to move as the operation progresses. The controller deploys the temperature sensors during the movement of the hydraulic support, so that the temperature sensors are arranged in the goaf, realizing automatic deployment. After that, the temperature information of different positions in the goaf is collected through the temperature sensors. The temperature sensors are directly deployed in the goaf to directly measure the temperature of the goaf. The obtained temperature data can intuitively reflect the situation of the goaf, and the data accuracy is high.

[0051] Afterwards, the collected temperature information is transmitted to the information processing equipment, which processes the temperature information to determine the spontaneous combustion risk areas in the mine where the temperature is too high and may pose a safety risk. Finally, the spontaneous combustion risk areas are displayed on the display device for users to view, thereby realizing the detection of mine temperature and avoiding the occurrence of safety accidents.

[0052] It should be noted that the temperature sensor can adopt a mine-use intrinsically safe wireless sensor; the process of transmitting temperature information can be realized through a mine-use intrinsically safe wireless repeater, a mine-use intrinsically safe wireless signal converter and a mine-use explosion-proof and intrinsically safe information transmission interface; the display device can adopt a mine-use explosion-proof display, and the information processing equipment can adopt a mine-use explosion-proof server; the controller can adopt a mine-use intrinsically safe controller.

[0053] Furthermore, the temperature sensor transmits the collected temperature information, so the temperature sensor has the ability to receive and send data. In order to ensure that the data transmission of the temperature sensor will not be affected by the static magnetic field in the mining area, in this embodiment, the specific implementation method is as follows:

[0054] The temperature sensor has six built-in antennas, three of which are transmitting antennas for transmitting data, and the other three are receiving antennas for receiving data. The three transmitting antennas and the three receiving antennas are arranged in an orthogonal manner, and the transmitting antenna is larger than the receiving antenna.

[0055] Among them, Figure 2 A temperature sensor antenna structure schematic diagram of a mine temperature detection method based on magnetic induction technology is provided. Figure 2(a) is a schematic diagram of the structure of three groups of transmitting antennas arranged in an orthogonal manner. Figure 2 (b) is a schematic diagram of the receiving antenna structure with three groups of orthogonal arrangements. By not sharing the same antenna for transmission and reception, interference between transmission and reception is avoided. At the same time, the transmitting and receiving antennas are nested together, and the size of the transmitting antenna is slightly larger than that of the receiving antenna, ensuring the data transmission distance.

[0056] Based on this, temperature sensors use magnetic induction technology for communication. Magnetic induction technology, also known as magnetic coupling technology, is a method of transmitting information using magnetic fields. The transmitting antenna of the temperature sensor transmits signals by changing the intensity or frequency of the transmitted magnetic field. Since magnetic fields can penetrate a variety of media, including soil, rock, and metal, magnetic induction technology has unique advantages in underground communications.

[0057] Furthermore, in the process of sending temperature information by the temperature sensor, the temperature information can be transmitted to the external temperature sensor in sequence through the temperature sensor located deep in the goaf, so as to achieve the purpose of sending the temperature information to the information processing device. In order to achieve this function, in this embodiment, the specific implementation method is as follows:

[0058] Determine the position information of the hydraulic support; number the temperature sensors corresponding to the hydraulic support according to the position information, and arrange the temperature sensors based on the numbering results; collect the temperature information through the temperature sensors.

[0059] Among them, by numbering the temperature sensors and associating the numbers with the location information of the goaf, the information transmission direction of the temperature sensor is clarified. For example, the number of the temperature sensor deep in the mining area is smaller, and the number increases as the location moves outward. Then the transmission direction of the temperature information can be understood as from the temperature sensor with a small number to the temperature sensor with a large number, thereby realizing the transmission of the temperature information deep in the goaf out of the mining area.

[0060] Based on this, the controller automatically calculates the moving distance of the hydraulic support and automatically completes the deployment of the temperature sensor according to the pre-configured deployment step. In addition, the controller has statistics on the inventory data of the temperature sensors and the number of deployments. When the number of built-in temperature sensors is insufficient, an alarm will be issued to remind you to replenish the temperature sensors in time. Before deploying the temperature sensors, the controller activates the temperature sensors. The activation process can be understood as writing the logical number to the temperature sensor, so that the temperature sensor has a wireless relay function. In addition, the controller can also adopt the master-slave networking mode. When the master controller fails, it will automatically switch to the backup controller to deploy the temperature sensor. At the same time, the local and server will issue alarms to prompt human intervention.

[0061] When the temperature sensor is deployed and a wireless connection is automatically established, the temperature information is collected and transmitted according to the number of each temperature sensor.

[0062] Furthermore, based on the preset information transmission strategy, the temperature sensor transmits the temperature information to the information processing device through magnetic induction. In this embodiment, the specific implementation method is as follows:

[0063] Based on the numbering result, any temperature sensor sends the temperature information collected by itself and the temperature information collected by the previous temperature sensor to the next temperature sensor, until the last temperature sensor transmits all the temperature information to the information processing device.

[0064] Among them, it can be known from the above that the temperature sensors are numbered before being deployed, and are deployed in sequence through the controller in the order of the numbers. In actual application scenarios, due to the different mining depths of the mining area and the different geological looseness of the mining area, the spacing of the hydraulic supports is different, which leads to the number of hydraulic supports being not fixed, and the corresponding number of temperature sensors is also not fixed. However, since the information transmission distance of the temperature sensor is affected by factors such as the mining environment and equipment cost, in actual application scenarios, the temperature sensor usually needs to be evenly arranged in the horizontal space by setting a fixed deployment distance, such as Figure 3 As shown in the schematic diagram of the temperature sensor layout of a mine temperature detection method based on magnetic induction technology, the temperature sensor will determine the number of monitoring routes according to the length of the mining face. According to the measured data, the optimal layout is to arrange a temperature sensor every 50 meters. The measured data of the wireless sensor communication distance tested according to the characteristics of the goaf shows that the optimal method is to place temperature sensors at 1 / 2 of the average communication distance in each route.

[0065] Based on this, the temperature sensor acts as a relay node for transmitting temperature information. Taking the transmission of data from a small-numbered temperature sensor to a large-numbered temperature sensor as an example, temperature sensor No. 1 sends the collected temperature information to temperature sensor No. 2, temperature sensor No. 2 sends the temperature information sent by sensor No. 1 and the temperature information collected by itself to temperature sensor No. 3, temperature sensor No. 3 sends the temperature information collected by temperature sensors No. 1 and No. 2, as well as the temperature information collected by itself, to temperature sensor No. 4, and so on, until all the temperature information is transmitted to the information processing device.

[0066] Furthermore, in order to monitor whether the temperature information transmission process is successful, a response mode can be introduced. In this embodiment, the specific implementation method is as follows:

[0067] After receiving the temperature information sent by the previous temperature sensor, the arbitrary temperature sensor sends a response signal to the previous temperature sensor, and after sending the response signal, sends the temperature information collected by itself and the temperature information sent by the previous temperature sensor to the next temperature sensor.

[0068] Furthermore, for the first temperature sensor, there is no previous temperature sensor, so it is impossible to adopt a mode of sending the temperature information collected by itself after receiving the temperature information from the previous temperature sensor. Then, regarding the process of the first temperature sensor sending the temperature information collected by itself, in this embodiment, the specific implementation method is as follows:

[0069] The first temperature sensor sends the temperature information collected by itself to the second temperature sensor at a preset sending time interval.

[0070] Furthermore, if any temperature sensor is damaged, a "breakpoint" will occur in the data transmission process, which will eventually cause all data to fail to be uploaded normally. In order to avoid this situation, in this embodiment, the specific implementation method is as follows:

[0071] When any temperature sensor does not receive the temperature information sent by the previous temperature sensor within the sending time, it will actively send the temperature information collected by itself to the next temperature sensor after waiting for a preset waiting time.

[0072] Furthermore, in addition to the next temperature sensor of the damaged temperature sensor, the previous temperature sensor of the damaged temperature sensor needs to skip the damaged temperature sensor. In this embodiment, the specific implementation is as follows:

[0073] After any sensor sends temperature information to the next temperature sensor, if it cannot receive a response signal sent by the next temperature sensor, it will skip the next temperature sensor and send temperature information to the next temperature sensor according to the numbering result.

[0074] Among them, in the process of temperature sensors transmitting temperature information according to their own numbers, taking the transmission of data from a temperature sensor with a small number to a temperature sensor with a large number as an example, sensor No. 1 will start sending data to temperature sensor No. 2 every T seconds. After No. 2 receives the data, it will send a response signal to sensor No. 1, and then immediately send data to temperature sensor No. 3, and so on.

[0075] Based on this, assuming that temperature sensor No. 3 fails, temperature sensor No. 4 does not receive data sent by temperature sensor No. 3 within T seconds, then waits for t seconds. If it still has not received data from temperature sensor No. 3, it actively starts to transmit data to temperature sensor No. 5; after temperature sensor No. 2 sends data to temperature sensor No. 3, if it does not receive a response signal from temperature sensor No. 3 within a preset time, it skips temperature sensor No. 3 and sends data to temperature sensor No. 4. At this time, if temperature sensor No. 4 is also damaged, it sends data to temperature sensor No. 5, and so on. However, in actual application scenarios, due to the data transmission distance problem of temperature sensors, generally at most 3 temperature sensors can be skipped.

[0076] In addition, if a temperature sensor is damaged, the damaged temperature sensor is skipped to send the temperature information, and the information processing device receives the number data in the temperature information, determines the number of the skipped temperature sensor, and generates a corresponding warning instruction. It should be noted that the temperature information sent by any temperature sensor contains number data, which records which numbered temperature sensor the temperature information was collected by.

[0077] In addition, the controller arranged on the hydraulic support can automatically calculate the moving distance of the hydraulic support when the position of the hydraulic support moves through the built-in inertial navigation method, and then determine the position of each temperature sensor. The number of the subsequent temperature sensor is associated with the placement position of the temperature sensor, and the corresponding placement position can be determined by the number of the temperature sensor. When the hydraulic support is moved, each temperature sensor automatically completes the wireless networking, combines with the preset mine intrinsically safe repeater to provide routing relay for the wireless signal, and combines with the preset mine intrinsically safe wireless signal converter to complete the conversion between wireless signals and Ethernet signals. In addition, a battery can be built into the temperature sensor. According to actual measured data, the temperature sensor with a built-in battery can work continuously for more than 2 years.

[0078] Furthermore, according to the temperature information, the process of determining the spontaneous combustion risk area by the information processing device is specifically implemented as follows in this embodiment:

[0079] A temperature cloud map is constructed according to the location information of the temperature sensor and the corresponding temperature information; and the spontaneous combustion risk area is determined by the temperature cloud map.

[0080] Furthermore, the process of determining the spontaneous combustion risk area through the temperature cloud map is specifically implemented as follows in this embodiment:

[0081] Based on the temperature cloud map, the spontaneous combustion risk area is calibrated by a preset spontaneous combustion risk judgment criterion.

[0082] Among them, the temperature at the corresponding position of the mining area can be determined through the location information and temperature information of the temperature sensor, and then the temperature in the area where the temperature sensor is arranged can be supplemented through the interpolation algorithm to construct a temperature cloud map. After that, the area with a temperature higher than the preset temperature threshold is marked as a spontaneous combustion risk area through the temperature cloud map, or the area with a temperature increase difference higher than the preset threshold within a period of time is marked as a spontaneous combustion risk area. And after constructing the temperature cloud map, the temperature cloud map can be input into the pre-trained neural network model to predict the spontaneous combustion risk area through the neural network model.

[0083] In addition, different temperature intervals can be set, and different temperature intervals correspond to different spontaneous combustion risks, such as low risk, medium risk and high risk. It should be noted that the number of temperature intervals that can be set is not limited. The actual temperature interval and its corresponding spontaneous combustion risk level are determined by the user's actual application needs, and this embodiment does not limit it.
